Product Introduction: STN3N40K3-VB MOSFET
STN3N40K3-VB is a high-voltage single N-channel MOSFET in a SOT223 package, suitable for high-voltage power management, switch control and power conversion applications. This MOSFET uses planar technology and has a high drain-source voltage (V_DS) of 650V, suitable for high-voltage switching and power conversion systems. Despite its high voltage tolerance, its on-resistance is 2500mΩ (@V_GS=4.5V) and 2000mΩ (@V_GS=10V), making it perform well in high voltage and low current applications. With a maximum drain current of 4A, the STN3N40K3-VB is widely used in high-efficiency power supplies, power conditioning, motor control and other power conversion modules.
